Silly Doom trivia question for anyone who ISN'T following my tumblr:So someone implied Doom (1993) rendered triangles. I pointed out that it does not, it's solely rendering line strips for walls and sprites, and weird horizontal strips for floors. HOWEVER: I was wrong. Doom DOES render triangles. But where does it render them? Because it's only one specific place. (Outside of level designers making triangular rooms. That doesn't count)

@foone DOOM’s triangle rendering is for the doritos product placement

@fooneI'm gonna say the vector map because I can't think of anything else that isn't a sprite, wall or floor

@foone isn’t there a triangle that represents the player in the map view? (I’m going on very sketchy memories here.)

@kemayo close! But it's an arrow, not a triangle

@StellaFoxxie in modern ports, yes. In the original doom, nope.

@AcornSquashbuckler nope. Those are raycasted invisibly or they're sprite based. No triangles needed

@razze close! But normally there are no triangles in the map view: just sectors and the player arrow (which isn't a triangle)

Since a few people have gotten it:It's the automap, but only if you use the IDDT cheat code. That enables drawing triangles around objects/enemies.

@foone I have read @fabinou 's book and I'm wracking my brain and....I've got nothing. Something related to the skybox is my shot-in-the-dark-pretty-sure-it's-wrong guess.

@foone as someone who's current project's renderer ended up way more doom-like than originally intended, you're talking about the map right? Triangle rasterization wouldn't even be useful in an engine drawing with vertical strips, though i suppose technically possible if you drew it like a sprite. Could also almost count floor slopes as triangle rasterization but the vanilla engine doesn't support that.

@raptor85 yeah! there's no need for triangles if you're drawing with vertical or horizontal strips, which is how Doom does all the main rendering. The only place it needs triangles is on the automap

@foone honestly I didn't even know that's how that cheat rendered, i always either played normal or went all the way with idfka, lol. Just nowhere else in the engine makes sense. (I LOVE classic rendering methods)

@foone you have to use it twice to see the triangles. First time just reveals the whole map.
